Right, it's a laptop...

The beeps are the results of a Power On Self Test (POST)
It could be main memory problem from the Beep code.
Disconnect it from the mains, take the battery out.
you'll find a small 'trapdoor' held in with a small screw.

Carefully remove this, you'll see a small pcb that's more chips than pcb.

Now you can see the main memory, it will have a connector on 1 edge and clips on opposite edges.

Important:- Ground yourself from static, i.e. don't stand on a carpet in your fave Nikes. If you don't have a static strap, or know what one is. Then a bare foot on a tiled or concrete surface is good.

1. flip the 2 clips with your thumbnails, and the module should pop out. lift carefully avoiding touching the bare connector.

2. check to see if there is any crud on the connector or removed card.

3. If clean, place card back into connector at a 30 degree angle rock down and up a couple of times, and then press home, the clips should click.

The card will stay put without the cover on. But I suggest you replace the cover.

Put battery back in and try it again.

With any luck it was just a bad connection on the ram card.

Regards

Philip

Why does my computer light come on but want boot and want show a screen and making a beeping sound


In simple terms, you have a hardware failure, probably in your motherboard, hard drive or memory.

The beeps your hearing, are there for a reason. The way it works, is, when you first turn a computer on, it goes through a "Power-on, self test", (know as a POST).

During this period, the BIOS queries the system hardware, such as the hard drive controller, the i/o ports, the memory, etc. and expects to receive back a specific return code which indicates that the specific hardware is running properly.

If it finds a failure in some element of the hardware, it will issue a specific pattern of beeps to tell you which part of the system is failing. (It does this because the system may be unable to display the error on the screen).

Each of the different BIOS manufacturers (BIOS is an acronym for "basic input output system, the hardwired code that talks to the actual hardware), have their own series of short and long beeps, for the different type of failures. So to know where the failure is, you must first know what BIOS manufacture you have in your computer.

Some of the more popular manufacturers are: AMI, Award, IBM, Phoenix, Macintosh, etc.

When you first turn on our computer, the display will report which brand of BIOS you have, and its version.

Once you determine the brand, you can go to any number of web pages that have a cross-reference for the beeps for each brand on BIOS.
I think most adhere to the old IBM PC beep codes as follows:
No beeps: no power, bad CPU,
1 beep: normal
2 beeps: POST/CMOS error
1 long beep, 1-short beep: motherboard problem
1 long beep, 2-short beeps: video problem
1 long beep, 3-short beeps: video problem
3 long beeps: keyboard error
Several long beeps: memory failure (most common fault)
Continuous hi-lo beeps: CPU overheating

You can check with the following websites to get an idea of what's going wrong.
Computer POST and beep codes
How to Diagnose Computer Beeps eHow

Often times a SIMM has come loose in its slot (or corrosion on the connector tabs). If your getting a memory error, you can try opening the box and try re-seating each of the memory Simms to see it that might be the problem. (When you have them out, look at the row of pins along the bottom and see if any look corroded.)

What was the last thing you did on your computer before this happened?
Did you change any system settings in the BIOS?
Did you add new software? or update any software or drivers?
Did you add any new hardware?
Is your system BIOS infected with a virus?
Because it appears that your PC is hanging up during the Power-On-Self-Test [POST]

Here's what happens; when the power is turned on, the computer BIOS [Basic Input/Output System] runs a POST (Power-On Self-Test). It is a diagnostic testing sequence that the computer runs to determine if the hardware [like the mouse, keyboard, hard drive, etc.] is working properly.

If the necessary hardware is detected and found to be operating properly, the computer begins to boot; If the hardware is not detected or is not operating properly, the BIOS issues an error message.

The error message may be a text on the display screen and/or a series of coded beeps, depending on the nature of the problem.

The series or pattern of beeps may vary...they may be in a number of long or short beeps or a mixture of long and short beeps, or even one long continuous beep, depending on what type of BIOS is installed.

Since POST runs before the computer's video card is activated or the integrated graphic chip on the main board, it may not be possible to progress to the display screen.

So if an error is detected during the POST it will halt the boot process because the hardware is essential for the computer's functions.

How many beeps do you hear during the initial POST?

You may have a burned out video chip/card; or corrupt drivers; or even an IRQ [Interrupt Request] conflict.

IT is either one of three things. 
  1. keyboard missing; check it's plugged in.
  2. graphics card; check that it has not been dislodged and is seated properly.
  3. memory. Are the memory cards properly seated?
